Error Message - Unknown Xero Exception

I am unable to download any data from our Xero system to excel using Datadear and I am unable to even report the problem on Excel i keep getting the following message - Unknown Xero Exception.

Hi @finance

Are you getting this error in a specific report or is this showing up on every request? For example can you download the accounts data table?

Reconnecting the Xero organisation seems to solve the issue.
